TO ALL WIIOM II MAY CONCERN:

Be it known that I, CHARLES O. YALE, of Rome, Oneida, county, New York,have invented a new and improved Corn-Husker; and I do hereby declarethat the following is a full, clear, and exact description of theconstruction and mode of operation of the same, reference'hcing had tothe annexed drawings, making` a part of this specification, in whiehFigure l is a sectional View through-the centre ot' the machine.

N, spurred gear on front of D, gearing into N1; u. like gear on a pin inthe frame giving motion to rN2, the gear on front of shaft of reel,which gears into N5, a gear like N, and which gears intol N, of likesize, which hason its shaft a larger wheel,

N5, which :gears into L5. The upper roller, C, may be of wgod. It ismuch larger than the under one, D, and is eet a little in advance olit.vThey are in bearings, E E, attached to the top of the back end of theframe, as seen in figs. 2

and 4. A There are rubber or other proper springs, El El, over the axisof C, to allow it to accommodate 'itself to the constallrs. Thedrivingfpulley or crank D1 is on the front end of .the axis of D, andthe upper roller, C, is driven by. an endless cord', D, passed aroundthe pulleys D3, D4, and C1,`a`nd the pulley-block D5, while the spring Dallows sufficient play to the cord to permitiC to rise and fallaccording to the size of the cornstallfzs. v The fnlerum D7 is under'D,and is best formed of plate ,metal curved up in front of D, with itsrear end extending to the top lof the hopperZ i In front of C and D, buta little lower, is the reel F. 'It has a central shaft, with twocircular ond plates, or may be cross-arms, and, say six rods, F1 Fl, andis driven by gearing N2, which receives motion from N. The rods F1 F1press down the ears of corn against the fulcrum D7, and break them off,which fall into the lhopper Grat the back end of the machine, and underG and D. A I

From the hopper the ears of corn are taken up one byfone, by theconveyor H, which is in form something like a water-wheel with buckets.Intermittent motion is given to it by the arm Hl on the slide/Land it iskept from turning back by the catch or stop H2, attached to the frame A.The slide I is divided' into two parts at its front end, one of which ison the inside, and the other'on the outside of the wheel I,'which is onthe shaft of N and N".v On each s ide ofI1 are two pins, Ig I2. y Oneset push against the end of one division ofthe slide, and the othersetengage in a notch on the other half and draw it back. -Thus it movestwice each way for each revolution of the wheel. p

Between thel conveyer and husking-rolls is a plate, K, and` directlyovcrthis plate is an arm, I3, attached to the slide. l l v v Thehusking-rolls are two, L and L. The front'one, L, should be covered withIndia rubber,.cloth, cord, or the like, and the other, L1, has anIndia-rubber tubing, L2, of much larger size than the roll itself, asseen in figs. 1 and 5. These rolls are made small, of about the size ofD. Ll should be somewhat less than the other, that the tubing may rotateyregularly without slipping or being rubbed by L. Such dilierence willof course depend on the thickness of the tubing. L1 has a pinion, L5, onits front end, which is driven by N5, and each has a pinion on thebackend, L4 L5, by which L is driven. y

Directly over the huskingrolls is a. series of rings, M M, on a smallrevolving horizontal shaft, in the form of pinion-wire, driven by a oordand pulley, connected with the pulley on the back end of the reel F3, asseen in lig. V3. These rings M are toothed on the inside and outside,and as the shaft revolves they are carried round with it. Thaou'tsideteeth are like those of a' slightly-indented circular saw. '.lo givefree motion to therings, a disk is interposed between them, as seen iniig. 2.

The operation of the corn-husker will be obvious from the descriptionalready given. The stalks are laid on the table B with the butts againstthe rolls C and D, and the machine started by hand, horse,or/stelam-powcr, and the stalksare drawn in until the ear reaches therolls. The greater size and forward position of the upper rolldepress'the point of the ear so that the reel in its revolution willreach it and press the stem against the fulcrum D7, and break it oil,and thestalk, now freed, passes over'the back e'nd of the fulorum orguard beyond the machine, and the ear,-guided by F2, falls into thehopper, and thence into one of the buckets of the conveyor, and at'eachforward motion of the slide I, the arm Hl will move up the ear one step.When it has passed over the top it will then fall over the arml, and onto the plate K, and the arm I3 moved forward by the slide I, pushes itforward over K towards thehusking-rolls and under therings MYM. Thesurface of K is pointed and rough, and so is the face of the arm I3. Thelatter holds the ear from turning, while the surface of Kl loosens thehusk on the under side, which enables the `husking-rolls the morereadily to take hold of it. The vhusking-rolls now seize the husk, whilethe-weight of the ringsM presses evenly on the ear, and the outer teethcause it to turn around, and the whole is readily removed. In the meantime another ear has been pressed forward by the arm I3, which'forcesout the hushed ear, when the husk is removed from -the second lone, andit is forcedout by a third one, and so ou.

Instead of making the conveyor as described, it may be in any otherconvenient form, as an endless apron, and the motion maybe continuousinstead of intermittent. Instead of gearing as.described, pulleys andbelts, or cords or spurredwheels, with chains, may be used in lthemanner which will readily occur to the competent mechanic, and motionmay be given to the slide I by a crank or other proper moans, instead orin the manner described. The roll C may be of the same size as D, and itmay also .be directly over D, instead of being placed inI advance ofit.Instead of the reel being of the form described, it may be so made as tohave an arm move forward and press oli` the ear, and then recede insteadof having a rotary motion, andthe arms Fl may be covered with rubber orthe like, to prevent injury to the corn. f v

Having thus described my invention, what'I claim therein as new, anddesire to secure by Letters Patent, is` 1. The rolls C and D, in' eitherform as described, in combination with the reel F, or its equivalent,for the purposes'mentioned.

2. The pulleys 01,".03, D4, and D5, endless cord D2, and spring D,constructed and arranged substantially as described and for the purposesmentioned. p

3. The conveyor Hand arms Hr and H?, constructed and arranged'substantiallylas described," and for the uses and purposes mentioned.l y

v 4. The conveyerH and the hashing-rolls L and Lf, constructedandarranged substantially as described, andlfor the uses and purposesmentioned. y

5. `The rings M M, constrcted and arranged substantially as described,angl foi' the uses and purposes mentioned. i

6. The plate K and the arm I3, constuctecl and arranged substantially asllescribed,l and for the uses and purposes mentioned. i
